CROSSLINKED PRODUCT OF CYCLIC OLEFIN RESIN, AND PROCESS FOR PRODUCING SAME

摘要

A crosslinked product of a cyclic olefin resin can be prepared by crosslinking a copolymer of a linear olefin and a cyclic olefin with an electron beam or the like. The cyclic olefin comprises a bicyclic olefin. The content ratio of the cyclic olefin is more than 15 mol% and up to 40 mol% relative to the total amount of the linear olefin and the cyclic olefin. The copolymer of the linear olefin and the cyclic olefin has a glass transition temperature of 20-80ºC or has a degree of crystallinity of 1% or less. The crosslinked product may have a haze value of 2% or less. The crosslinked product according to the present invention has both heat resistance and flexibility while keeping a low haze value and high transparency.
